WILLIAM WARNER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HIM- SELF, H.MCILVAIN, J. L. WARNER, AND GEORGE O. SHARP.

, IMPROVED CAR-BRAKE.

Specification forming part of Letters Patent N0. 53,365, dated March 20,1866.

To all whom it may concern:

Be it known that I, WILLIAM WARNER, of the city and county Philadelphia,and State of Pennsylvania, have invented a new and useful Improvement inGar-Brakes; and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same,reference being had to the annexed drawings, making a part of thisspecification, in which- Figure 1. is a plan or top view of a cartruckwith the improved brake attached. Fig. 2 is a vertical longitudinalsection of the same at the red line 1 2 of Fig. 1.

Like letters in both figures indicate the same parts.

The nature of my invention will be understood by the followingdescription.

A is the truck of an ordinary car. B B are the axles of the wheels 0 O OG. On said axles I confine the cylinders D D D D, which are encircled bythe coilsprings E E E E, the nearest points of the springs being ashortdistance therefrom, as seen in Fig, 2, when the brake is not applied.The springs are confined at one end, by means of bolts or screws 1), tothe quadrilateral frames F F, respectively, and at their other end tothe pullingbars G G. The said frames F F are confined to thelongitudinal pieces of the truck by means of bolts or screws 0, and aresustained at their lower sides by means of the bent rods H H, asrepresented in Fig. 2. There is confined to said rods a cross-bar, I,which receives the lower end of the swivel-shaft J, which hasacross-rod, K, connected at each end, in the usual manner, with thecrank-shafts L L by means of the chains M M and cylinders N N. To thepulling-bars G G, I connect one end of the chains 0 O, and the other endof each to the cross-bar K of the shaft J, as represented in bothfigures.

The operation is as follows: When the brake is not operated the springsE spring off from the cylinders D D, so as to allow a free turning ofthe latter; but when the wheels 0 are to be checked one of thecrankshafts L is operated in the usual manner, which gives motion to therod K, so as to draw the chains 0 O, and consequently the pulling-bars GG, so as to make the springs E hug the cylinders D and check the forwardmovement of the car.

Having thus fully described the construction and operation of myimprovement in carbrakes, what 1 claim therein as new, and desire tosecure by Letters Patent, is

1. The use of the coil-springs E, in combination with the axles B, bymeans of the cylinders D, when arranged and operating substantially inthe manner hereinbefore described.

2. Combining the springs E with the frames F and pulling-bars Gr,substantially as and for the purpose set forth.

In testimony that the above is my invention I have hereunto set my handand affixed my seal this 28th day of October, 1865.
